The "X Factor" finale airs tonight, and it's going to be a star-studded affair!

Finalists Chris Rene, Melanie Amaro and Josh Krajcik will each be paired with a celebrity duet partner. Us Weekly was the first to report the pairings, detailed below:

Chris will perform "Smile" with Avril Lavigne.

Melanie is singing with R. Kelly. Our guess is that they'll be belting out the inspiration ballad, "I Believe I Can Fly," but her song has yet to be confirmed.

Josh will rock out with Alanis Morissette, but their selection has yet to be announced.

Also performing during the finale are Justin Bieber, Ne-Yo and Pitbull, but all eyes (and ears) will be on the top three. Who deserves the $5 million recording contract? Vote in the poll below!
